Got a Hi-Capa airsoft pistol but want to make some personalizations or customizations to improve performance?

Check out these Hi-Capa parts and get going.

COWCOW PinkMood Enhanced Loading Nozzle Set

Designed for use with Tokyo Marui Hi-Capa and 1911-style airsoft pistols, the COWCOW PinkMood Enhanced Loading Nozzle set features injection molded polymer construction, high-impact resistance, and a non-rotating valve.

It features a durable, stable valve pin lock and increases nozzle diameter to 14mm which significantly boosts performance.

COWCOW NP1 Nozzle Spring

The COWCOW NP1 Nozzle Spring upgrade is made with high-strength steel and substantially stabilizes nozzle movement.

The draw here is self-evident. Upgrading your airsoft pistol with a Hi-Capa part like this will improve performance and power – boosting it by as much as 180% during cycling.

Airsoft Masterpiece Limcat “Speedcat” Slide

The Airsoft Masterpiece Limcat “Speedcat” slide may be named for marketing hype. Then again, it might boost performance.

Compatible with 5.1 Hi-Capa and 1911-style airsoft pistols and available in a wide range of colors, the “Speedcat” is lightweight, precision-crafted, and highly durable.

With its uniquely situated cutouts, it might even give a slight boost to cycling time, enabling even faster shot strings.

Who knows. It’ll definitely make your Hi-Capa a lot cooler.

Laylax Nine Ball Gas Route Seal for Hi-Capa Pistols

The Laylax Nine Ball Gas Route Seal for Hi-Capa airsoft pistols might be one of the most unassuming upgrades you can make.

But this Hi-Capa part may also represent one of the most impactful.

Drop-in ready for installation, the Laylax Nine Ball Gas Route Seal improves both gas flow and gas seal with a redesigned seal shape.

This potentially increases the power of your GBB airsoft pistol and it definitely reduces gas loss between the mag and nozzle.

Shoot faster, boost power, and stretch gas canister capacity with this basic upgrade.

Maple Leaf Decepticons 70-Degree Bucking

These 70-degree hop-up buckings are aggressive, not only suitable for use in select Hi-Capa gas pistols, but in some gas rifles, too. (70-degree buckings are recommended for airsoft guns that shoot between 355 and 460 FPS).

The unique concave hop-up system is designed to be used with the Maple Leaf Tensioner system, and this bucking has another trick up its sleeve.

Made from durable yet flexible silicone, you can use them in the cold, too. They won’t get hard and brittle like some other buckings.

Airsoft Masterpiece Brass Hop-Up Base

This drop-in-ready brass hop-up base for Hi-Capa airsoft pistols represents a sizable upgrade that, while easy to make, will increase the durability of the platform.

Made of high-quality brass, it’s very corrosion-resistant and very strong.

COWCOW RS1 Recoil Spring

Sometimes it’s the Hi-Capa parts behind the scenes that pull the most weight.

Case in point, this COWCOW RS1 Recoil Spring.

Designed for Tokyo Marui 4.3 Hi-Capa airsoft pistols, these recoil springs are made of high-strength spring steel and are coated for corrosion resistance.

Most importantly, they can boost power between 120% and 140%, and feature a shorter length that produces harder recoil and improves cycling efficiency.

Maple Leaf Crazy Jet Tight-Bore 6.04mm Inner Barrels

What can we say? These Maple Leaf Crazy Jet Tight-Bore Inner Barrels create a cushion of air around the BB as it exits the barrel, stabilizing the BB, and improving both accuracy and range.

Considering how affordable these are, and how expensive some other Hi-Capa parts are, it seems like this upgrade is a no-brainer.
